I got my ls all swapped in and running. One problem that I am running into is shifting. When its off it shifts great. But after I start it up it will not shift it just wants to grind. Also when I start it in gear with the clutch pushed in, it wants to slightly move. I am running a 91 ls trans, 91 clutch disc (new), 91 Throwout (New) and a New 95 ls hydro pressure plate. Thought all pressure plates were the same. Could the pressure plate be the problem? because it seems like I have no pedal for the most part. but it still shifts like it should when its off.
